Insights
Estimating atherosclerotic cardiovascular disease (ASCVD) risk in adults aged 40-79 is crucial for primary prevention. High-risk individuals (≥20% 10-year risk) should receive statin therapy, while intermediate-risk patients benefit from counseling and lifestyle modifications.
Area of Science:
- Cardiology
- Preventive Medicine
- Public Health
Background:
- Cardiovascular disease (CVD) prevention strategies are essential for adult health.
- Risk assessment guides primary prevention interventions.
- The American College of Cardiology/American Heart Association (ACC/AHA) recommends specific guidelines for CVD risk estimation.
Purpose of the Study:
- To outline the current recommendations for estimating and managing atherosclerotic cardiovascular disease (ASCVD) risk in adults.
- To emphasize the role of risk assessment in guiding statin therapy decisions.
- To highlight the importance of lifestyle modifications and ideal cardiovascular health metrics in CVD prevention.
Main Methods:
- Utilizing population-appropriate risk equations, specifically the ASCVD pooled cohort equations for US adults aged 40-79.
- Categorizing 10-year ASCVD risk into high (≥20%) and intermediate (7.5% to <20%) levels.
- Incorporating CVD risk enhancers, such as coronary artery calcium scoring, to inform clinical decisions.
Main Results:
- A 10-year ASCVD risk of 20% or higher indicates high risk, warranting statin therapy.
- Intermediate risk (7.5% to <20%) requires discussion of statin benefits considering patient preferences.
- Lifestyle modifications, including adherence to AHA's Life's Simple 7 (now 8 components), are universally recommended.
Conclusions:
- Risk-based assessment is fundamental for primary CVD prevention.
- Statin therapy decisions should be tailored based on calculated ASCVD risk and patient-specific factors.
- Promoting ideal cardiovascular health through lifestyle changes is key for primordial prevention.
Abstract:
As part of the approach to primary prevention of cardiovascular disease (CVD), adults should have their CVD risk estimated using a population-appropriate risk equation. In the United States, the atherosclerotic cardiovascular disease (ASCVD) pooled cohort equations are recommended by the American College of Cardiology/American Heart Association (ACC/AHA) to estimate risk in patients ages 40 to 79 years. A 10-year ASCVD risk estimate of 20% or higher is considered high, and patients having this level of risk should be offered and counseled to receive statin therapy. A 10-year risk estimate of 7.5% to less than 20% is considered intermediate, and clinicians should discuss the potential benefits of statin therapy for primary prevention in the context of the patient's preferences and values. In some situations, use of CVD risk enhancers, particularly coronary artery calcium assessed by computed tomography, may help inform the clinician-patient discussion. All patients should be counseled about healthy lifestyle modifications to reduce CVD risk. The AHA's Life's Simple 7 defines ideal cardiovascular health as no tobacco use; ideal blood pressure, blood glucose, and cholesterol levels; adequate physical activity; weight management; and healthy diet. An 8th component (sleep) was very recently added and 4 of the original components have been updated. These metrics provide goals that can drive efforts toward primordial prevention (ie, keeping risk factors themselves from developing).
